DETONATING DEVICE.

Application led October 24, 1921, Serial No. 509,790. Renewed July 5,1928.

rlhis invention relates to toy detonating devices of the type adapted toexplode successively a plurality of caps arranged, preferably, in acontinuous strip.

An object of the invention is to provide a device in which the caps maybe arranged in a magazine adapted to be advanced through the firearm sothat the usual hammer may engage the caps successively.

Another object of the invention is to provide a magazine in which astrip of caps may be readily inserted for use in a pistol or other typeof firearm.

A still further object of the invention is to afford a structure whichis simple and inexpensive to manufacture, efficient and positive in itsoperation, and in which the explosions take place entirely within acasing without danger to the operator.

Further and more specific objects of the invention reside in the detailsof construction and in the combination and arrangement of the severalparts, which will become more clear as the description proceeds.

In the accompanying drawings I have shown the invention as embodied in atoy pistol, although it should be understood that the invention might beapplied to other types of firearms and might be considerably varied fromthe illustrative details of construction shown in the drawings andhereinafter described.

Fig. 10 is a cross section on the line 10-10 of Figure 9, and

Fig. 11 is an elevational view of a modified magazine construction.

Referring to the drawings for a more detailed description, the pistolcomprises a case or shell shaped to form a barrel 10 and a handle orstock 11 to resemble a revolver. The shell is, preferably, cast orstamped and formed in two sections 12, 13, held together by bolts orscrews 13. The section 12 has a marginal flange 14 which meets the innerface of the section 13 and maintains the two sections spaced apart. Thebarrel is open at its forward end, as indicated .at 15, (Fig. 4) and therear end of the pistol is provided with a magazine inlet opening 16 sothat a magazine 17 may be inserted in the barrel and fed therethrough bya mechanism later to be described.

A trigger plate 18 (Figs. 2 and 8) is mounted within the casing forreciprocatory movement; and has a forwardly extending portion 19 and atrigger 20. The plate is supported upon the inner face of the casingsection 13 by means of a guide rib 21 (Fig. 7) upon the casing sectionwhich fits between two spaced guides 22 upon the inner face of thetrigger plate. The trigger plate is held in its forward position, shownin Figures 2 and 3, by means of a coil spring 23 anchored at one end,24, to the casing section 13, and at its other end, 25, to the triggerplate, a stop pin 26 upon the casing section extending through a slot 27in the trigger plate and limiting its reciprocatory motions in oppo-sitedirections.

A hammer 28 is mounted upon the trigger plate and has its forked shank29 extending beneath a strap 30 upon the trigger plate and bent upwardlyto prevent withdrawal ofthe trigger from the anchoring strap. The strapfits loosely about the end of the hammer so as to permit the latter tobe raised as the trigger plate is moved rearwardly as indicated inFigure 4. A leaf spring 31 having its rear end 32 fixedly secured in alug 33 upon the trigger plate extends forwardly above the hammer and isfixedly secured to the hammer as indicated at 34:. This spring serves tomaintain the striker portion 35 of lil the hammer projecting through anopening 36 in the forwardly extending portion 19 of the trigger plateand, as the hammer is moved rearwardly by the magazine during theretract-ion of the trigger plate t-he saring is flexed, all of which isclearly shown in Figure l.

Referring to the magazine which serves to raise the hammer as thetrigger plate is retracted, it is preferable that the magazine beconstructed so as to receive a plurality of caps arranged in strip form.The magazine comprises a face plate 37 having a plurality of openings 38and arranged adjacent each opening an outwardly and rearwardly inclinedtooth 3) which positioned in advance of the opening. The magazine isalso formed with a back plate et) slightly spaced between the ends ofthe magazine from the face plate so as to form a chamber to receive astrip of caps positioned within the chamber with a cap registering witheach opening. The lower edge of the magazine is provided with a seriesof shoulders el which provide an edge of rack formation, each shoulderbeing positioned beneath a cap opening. A spring stop or pawl .l2 isfixed in the forward edge of the guide rib 2l; and extends upwardly andforwardly so that its free end may successively engage the shoulders 41as the magazine is fed through the barrel.

ln using this device the magazine is lirst loaded with a strip of caps,a dctonating cap being located in registry with each opening in themagazine face plate. The magazine is then inserted in the rear barrelopening 16 until its forward edge comes into engagement with the strikerportion 35 of the hammer. The trigger plate and hammer are thenretracted by means of the trigger and during this movement the strikeris moved outwardly, as shown in Figure 3, by the lirst tooth 39 upon themagazine. As the retraction of the trigger is completed the strikermoves past the end of the tooth and is forcibly thrown against the capin the first magazine opening to explode the cap. During the retractionof the trigger plate and hammer the coil spring 23 has been extended andimmediately upon the release of the trigger the spring serves to returnthe trigger plate and hammer to the position shown in Figure 2. Duringthe return movement of the hammer and trigger plate the striker 35engages the rear edge of the tooth positioned in advance of the capwhich has been exploded and advances the magazine one step through thebarrel until the spring pawl 42, which holds the magazine stationaryduring the retraction of the trigger plate, engages the next shoulder 41upon the lower edge of the maga.- zine.

The above described operation may be con tinued successively until thecaps within the magazine are exploded, whereupon the magazine may bewithdrawn through the forward opening 15 in the barrel and relilled.

t will be observed that all of the explosions take place within thecasing which is entirely closed at the explosion point, and thus nosparks or other flying particles from the caps can leave the casing.

Particular attention is called to the extreme simplicity of thestruc-ture above set forth, it bein g observed that the hammer and itsopern ating spring are mounted entirely upon the trigger plate and maybe assembled therewith before insertion of the same within the casing.lt will also be noted that the hammer itself serves as the feeding meansfor the magazine, thus eliminating the' necessity for sepa ate feedingmechanism generally employed in toy pistols in which it is possible toexplode a plurality of caps in quick succession.

leferring to Figures 9, 10 and 11, there is shown a modified embodimentof the invention in which the principle of operation is the same as inthe pistol above described, but in which the mechanical construction ismaterially simpler, permitting production at considerably less expense.The pistol comprises a casing- 43 having a barrel portion all and astock or grip portion 45, the casing being preferably formed from sheetmetal; and may be suitably stamped out and bent from a single piece.rlhe casing encloses a trigger plate lo carrying the trigger 417; andthe trigger plate is held within the casing, as by means of a bolt 48passing through the stock of the casing below the trigger plate. rllhetrigger plate is formed from two strips of metal (Figure 10) suit-ablybent along a longitudinal line below their upper edges, as indicated at49, to form a magazine chamber 50 adapted to receive the magazine 51.The two strips of metal forming the trigger plate may be held togetherby a clip 52 at the rear of the trigger provided with a stop 53 adaptedto engage the casing when the trigger plate is moved forwardly, toprevent displacement of the trigger plate during the operation of thepistol. A hammer 5a having its head extending through an opening 55 inone wall of the magazine chamber and a spring shank 56 is held upon thetrigger plate by means of clips 57 struck up from the trigger plate. Atits forward end the trigger plate is surrounded by a tubular metal clip5S which has a portion cut away to permit the same to be slipped overthe forward end of the magazine chamber. This clip serves as a bearingfor the trigger plate as it is reciprocated within the casing, since ithas a comparatively tight lit within the barrel 44; and also assists theclip 52 in holding together the strips comprising the trigger plate. Themagazine 51 has the openings 38 and the hammer engaging teeth 39 inadvance of each opening just as the magazine 17 shovvn in Figure 7. ItWill be noted, however, that shoulders 4l are provided along the upperedge of the magazine so as to engage successively a spring holding-paivl60 mounted Within the barrel of the casing and held therein by a clip 6lstruck out of the casing.

A strip of caps is placed upon the magazine with the caps registeringwith the openings 38 and the curved edge portions 5l of the magazineengaging' the margin of the strip of caps and holding it in position.The

magazine is inserted in the chamber 50' through its open rear end andthe trigger plate is then reciprocated forwardly and rearwardly in thecasing to advance the magazine through the chamber and explode the caps.As the trigger plate is moved rearwardly, the hammer head engages aprojection 39 upon the magazine and is raised, the magazine being heldstationary by the retaining pawl which engages a shoulder il upon themagazine. Continued movement ot' the trigger plate results in the hammerhead striking the cap registering with the opening at the rear of theprojection and eX- ploding the cap. Upon subsequent forward movement ofthe trigger' plate, the hammer head engages the projection which it haspreviously passed over and carries the magazine forwardly with thetrigger plate. Continued repetition of the above movements causessuccessive explosions of the caps in the magazine and a feeding movementof the magazine through the chamber and barrel until the caps have allbeen exploded, Whereupon the magazine may be Withdrawn from the openforward end of the chamber to be refilled.

lt should be understood that numerous modifications may be made in theillustrated and described structure Without departing from the range ofthe invention.
